11.50 a. Often, the fatty acid released by the action of phospholipase A2 (see Problem 11.49) is arachidonic acid. Indirectly, the release of this fatty acid is linked to inflammation that arises at the site of a snake bite. Explain. b. The diglyceride (lysophospholipid) formed by the phospholipase A2-catalyzed breakdown of a triglyceride acts as a detergent that can disrupt cell membranes. Which more closely resembles membrane phospholipids, triglycerides or diglycerides
